COLOR-SLIDE-UPERATING MECHANISM.

Application filed November 29, 1924. Serial No. 752.921.

This invention relates to new and useful improvements in color slideoperating mechanism.

One object of the invention is to provide a mechanism for operatingcolor slides used in grading and testing oil.

Another object of the invention is to provide a mechanism for operatingthe color slides in grading oil whereby the slides will be protected andhe t clean and may be used without liability 0 breakage and whereby muchtime may be saved in the testing operation.

With the above and other objects in view this invention haspartiicularrelation to certain novel features of construction, operation andarrangement of parts, an example of which is given in this specificationand illustrated inthe accompanying drawings, wherein Figure 1 shows aside elevation of the device.

Figure 2 shows avertical sectional view.

Figure 3 shows a horizontal sectional view taken on the line 3+3 ofFigure 2, and

Figure 4 shows a horizontal sectional view taken on the lineHof Figure1.

Referring now more particularly to the drawings, wherein like numeralsof reference designate similar parts in each of the figures, thenumeral-1 designates thehousing of the mechanism, which is extendedlatorally at the bottom, as at 2.

lVithin the upper part of the housing there is a narrow, oblong, casing3, provided with any number of pairs of vertical channels 4i, separatedby partitions 5. The ends of the casing 3, as well as the. partitions 5,have aligned rectangular openings 6.

Color slides, as 7, move in the respective channels a. Each slide ispivoted to the up per end of an operating rod 8. This rod works looselythrough bearing slots 9 in the transverse platform 10 secured in thehousing. Above this platform each rod carries an annular stop 11,adapted to limit the downward movement of the rods by engagement withsaid platform 10. Spaced beneath the platform each rod 8 has a fixedseat 12 on which are seat-ed the coil springs 13 which surround saidrods and whose upper ends support the slidable stops 1 L adapted toengage against the under side of the platform 10. The lower end of eachrod 8 is ivoted to the inner end of a lever 15, said lhvers beingpivoted on the transverse rods 16, and pivoted to the outer ends of thelevers 15 are the operating keys 17 which work up through correspondingslots in the extension 2. These keys may be numbered to correspond withthe numbers of the corresponding slides 7. When a key is depressed thecorresponding slide 7 will be: elevated into alignment with the openings6. Each vkey has a lateral notch forming a shoulder 18 which may beengaged with the end of the corresponding slot, by moving the keylaterally, and the corresponding slide thus locked in elevated position,with its corresponding spring 13 undercompression. \Vhen the. key isreleased said spring will lower the elevated slide until thecorresponding stop 11 contacts with the platform 10.

Fitted snugly over the top of the housing there is a hood 19, preferablyof sheet metal, to protect the slides from dirt or oil, and having endopenings which align with open ings 5 and 6. At one end of the hood 19and offset from said h0od, at one side, and formed integrally therewith,there is an eye piece hood 20, having a rectangular opening 21. Behindthe eyepiece hood 20, and along side the hood 19 there is a platform22.This platforini-s provided forthe purpose of supporting the cells of oilto be tested.

These cells are merely oil containers, open at the top and havingtransparent ends and are filled with a sample of the oil to be graded,or tested, and are placed "one at a time, on the platform 22for thetest.

Extending out beyond the hoods 19 and 20 is a support 23, for the eyepiece 24:. This eyepiece will usually be the conventional Lovibond eyepiece now in common use. It has the sight opening 25, in its outer end,and is separated by the length wise, central, vertical partition 26.

Sometimes two, or more of the test slides are elevated into registrationin order to exactly match, in color, the oil being tested. The oil thustested is then given a number equal to the sum of the numbers of thetest slides used in making the test.

The cell of oil to be tested is placed on the platform 22 and the testslides 7 are ele vated one at a time, and inspected through the eyepiece, until a slide is found which corresponds to the color of the oilin the cell under test. The oil tested then given the number of thecorresponding color slide and its grade is thus fixed.

What I claim is fill 1 A device of the character described ineluding anupright housing, an oblong cas ing at the top of the housing, translucidcolor slides in said casing and vertically movable into upper and lowerpositions, a supporting platform fora test cell alongside said casing,means for manually moving each slide into upper position alongside saidcell, means for locking each'shde 1n said upper position, yieldablemeans for moving each slideinto lower position when said locking meansis released and an eye piece having a single sight opening through whichsaid cell and the associated slide may be simultaneously inspected.

2. A device of the character described including an upright housing, anoblong casing at the top of the housing provided with a plurality ofpairs of vertical tracks, a translucid color slide movable in each paircluding an uprighthousing whose lower end I is extended laterally, anoblong casing at the top of the housing provided with a plurality ofpalrs of vertical channels,'part1t1ons separating said pairs, the endsof said casing "and said partitions having openings, said openings beingin alignment, a color slide movable 1n each pair of channels, into upperor lower position, operating rods 1n said housing pivotedat their upperends to the respective slldes, bearmgs in the housing through which therespective rods work, a

stop on each rod above said bearing adapted to limit the downwardmovement of said rod, yieldable members surrounding the respective rods,a seat on each rod beneath its bearings, said yielda-ble members beinginterposed between said seats and the corresponding bearings, leverspivoted in said lat erally extended portion of the housing, eachconnected, at one end to the lower ends of the respective rods,operating keys pivoted to the other ends of said levers, the upper partof said lateral extension having slots through which said keys work, aspecimen supporting platform at the top of the housing alongside saidslides and an eye piece at the top of the housing having a lengthwisecentral vertical partition and a sight ope-ning at its iouter 'endthrough which said slides, when elevated, and the specimen to be testedonsaid platform may be simultaneously inspected.

l. A device of the character described including an upright housing, anoblong casat the top of the'housing, translucid color slides in saidcasing and vertically movable into upper and lower positions, asupporting platform for a test cell alongside said casing, means formanually moving each slide into upper position, alongside sa d cell,means for locking each slide in said upper positionand an eye piecehaving single sight opening through which said cell and the associatedslide may be simultaneously inspected.

In testimony whereof I have signed my name to this specification.
